Abstract:

In order to provide histological basis for molecular regulation mechanism of the growth of wool and cashmere,and provide reference for application of hair follicle traits in cashmere goat breeding,hair follicle structure and the correlation between characteristic parameters and cashmere production traits in Shanbei White cashmere goat were studied.Skin samples were collected from Shanbei White cashmere goats,and made into paraffin sections.The morphological characteristics of skin hair follicle were observed by microphotograph system and a number of parameters were measured.The correlation between characteristic parameters and cashmere production traits was analyzed with SPSS 17.0 software.The results showed that the hair follicles of Shanbei White cashmere goat were distributed in hair follicle groups and the main type of hair follicle group was three-type,which accounted for 85.80%.The cashmere yield had an extremely significant positive correlation with body weight,cashmere length,S/P value,SF-bulb width (P < 0.01),had a significant positive correlation with SF density (P < 0.05),and had a significant negative correlation with epidermis thickness (P < 0.05).The cashmere length had an extremely significant positive correlation with cashmere yield and SF-bulb width (P < 0.01),had a significant positive correlation with body weight,S/P value,SF diameter (P < 0.05),and had a significant negative correlation with epidermis thickness (P < 0.05).The cashmere fineness had a significant negative correlation with S/P value (P < 0.05).It was concluded that the skin hair follicle characteristics of Shanbei White cashmere goat,such as S/P value influenced the cashmere fineness,and body weight,cashmere length,S/P value,SF density (cashmere density) significantly influenced the cashmere yield (P < 0.05).It suggested that the S/P value could be used as a very important trait in Shanbei White cashmere goat breeding.High S/P value not only could improve the cashmere yield,but also could improve the cashmere length and reduce the cashmere fineness,thus solve the contradiction of improving the cashmere yield and quality at the same time.
